Comparison of boilers for treated and untreated waste

This paper presents the design and comparison of two boilers with the same steam output, but with different quality of incoming fuel. The first steam boiler is fed by low quality municipal waste without any treatment, which has a lower calorific value of 9.2 MJ/kg. In contrast to the first fuel, the second fuel is a sorted municipal waste with a lower calorific value of 16.3 MJ/kg. For the sizing of boilers, the same methodology of calculation is used, which ensures the comparability of these projects. The comparison includes the analysis of the fuel quantity supplied to the boilers, the size of the boilers and the combustion conditions.
